Bongo rode the elevator to the top of the monument.  At the top, he looked out at the land around the monument.  It was really swampy, which accounted for the bugs.  Bongo only saw one bug at the top of the monument, and that one looked REALLY tired.

Bongo was happy that he could ride the elevator and didn’t have to take the stairs.  He would have been as tired as that bug was.
